In physics, energy density is the quotient between the amount of energy stored in a given system or contained in a given region of space and the volume of the system or region considered.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...
Energy density is measured volumetrically (per unit of volume) in watt-hours per litre (Wh/L). Units of liters and dm 3 can be used interchangeably. As of 2013 commercial energy density varies widely, but in general range from around 5 to 8 Wh/L. In comparison, petrol fuel has an energy density of 32.4 MJ/L or 9000 Wh/L. [90]
